Street Modification Criteria and Analysis
(
Substantially implements the policy direction of the policies and objectives of the Comprehensive Plan Land Use Element and the Community Design Element and the proposed modification
is the minimum adjustment necessary to implement these policies and objectives.
Staff Comment:
The Community Design Element has applicable policies listed under a separate section labeled Promoting a Safe, Healthy, and Attractive Community. These policies address walkable neighborhoods,
safety, and shared uses. The intent of the policies are to promote new development with walkable places that support grid and flexible grid street and pathway patterns, and are visually
attractive, safe, and healthy environments. The requested street modification is consistent with these policy guidelines.

Will meet the objectives and safety, function, appearance, environmental protection, and maintainability intended by the Code requirements, based upon sound engineering judgment.
Staff Comment:
The City’s Public Works Transportation section and Economic Development section have reviewed 156th Avenue SE and the surrounding area and have determined that a modified minor arterial
street section is more suitable for the portion of 156th Avenue SE adjacent to the site. The determination was based on the fact that the roadway is directly adjacent to single family
residences and there is insufficient space between the existing right of way and existing homes to expand the roadway section to meet the minor arterial standards.
